| # | Input | Output |
|---|---|---|
| 0 | not connected because it is typically used for clocked designs and may be used in the future of this design | output signal ~E, i.e. the top and bottom segments light up, when the game is over due to an unattended situation on any river bank side |
| 1 | input signal F for the position of the farmer | output signal ~R i.e. the top-right and bottom-right segments light up, to indicate an unattended situation on the right river bank (game over) |
| 2 | input signal W for the position of the wolf | output signal ~R i.e. the top-right and bottom-right segments light up, to indicate an unattended situation on the right river bank (game over) |
| 3 | input signal G for the position of the goat | output signal ~E, i.e. the top and bottom segments light up, when the game is over due to an unattended situation on any river bank side |
| 4 | input signal C for the position of the cabbage | output signal ~L i.e. the top-left and bottom-left segments light up, to indicate an unattended situation on the left river bank (game over) |
| 5 | here be dragons or an easter egg | output signal ~L i.e. the top-left and bottom-left segments light up, to indicate an unattended situation on the left river bank (game over) |
| 6 | here be dragons or an easter egg | |
| 7 | output signal A to light up the "dot LED" of the 7 segment display as an indicator that all objects have reached the right bank of the river and the game is won! 🎉🎉🎉 |
